  1. “Engine Oil Pressure Too Low”

    I remain unconvinced that this issue is solved in post-20 B58TU engines. Here is a '21 Supra with a failed oil pump replaced under warranty. https://www.supramkv.com/threads/can-you-measure-your-oil-in-i-drive-after-driving-for-30-minutes.18569/#post-292413
  2. Brown Coolant

    Ok. I asked because I had suspected there was a previous owner that inappropriately mixed coolant types. If the wrong coolant goes into the system, it can create corrosion with bad reactions to the metallurgy of the coolant loop. The corrosion makes things look dirty and brown. My advice is to...
  3. Brown Coolant

    Are you the first owner of the vehicle?
  4. “Engine Oil Pressure Too Low”

    I suspect your oil pump has failed. This would be covered under warranty, and (except in very specific circumstances that are probably not applicable to you) would not be caused by the tune. You can either let the dealer handle this, or do a DIY oil pump replacement. I haven't checked in a...
  5. Best stock location 2 port T51R turbo

    Same on my 65 Omega. One and done. Although I have seen, and personally helped fix, a number of WG arms that seemed to baffle "professional installers." Not sure they spend a lot of time around EWGs, or whatever the generous and compassionate reason might be, but they certainly couldn't admit...
  6. New 2025 High-performance A90 Final Edition announced for JP/EU/AU (No GRMN - S58)

    As an aside, this quote from the press release is written in just such a way to imply that there's a future: New high-performance, high-specification GR Supra A90 Final Edition is the ultimate expression of the current generation My day job includes writing copy that makes it into press...
  7. New 2025 High-performance A90 Final Edition announced for JP/EU/AU (No GRMN - S58)

    Pretty comprehensive, as far as "last calls" go. In comparison, Dodge has been charging $100K for a new shade of grey on the Durango. A level of uninspired lameness I have come to expect not only from Dodge, but from every automaker wrenching out the last few pennies of an aging platform. I'm...
  8. Custom MHD tuner in Phoenix? Or remote recs?

    Sumo for remote tuning. Super communicative, solid pricing, good tuner.
  9. What's your opinion on this?

    Putting on my serious hat for a moment: I don't believe there is any intellectual value in seriously dropping the "China turbos" line. Pretty much every turbo on earth is, at this point, assembled wholly or partially from components made in China. It's a vapid brainrot comment designed to end...
  10. 2022 Supra - Clinking sound from front wheels during high lateral force.

    There is a TSB for many BMW models, including our platform mate G29 Z4, concerning ticking sounds coming from the front rotors under high load. The TSB is SI B34 05 17 for anyone who has access to BMW bulletins. Depending on the car, the solution is a very thin friction ring between rotor and...
  11. Does anyone have a guide or in depth diagram of the engine sensors/hoses/harness

    A diagram of every system in the car. You can also download the shop manual. PDFs are widely available.
  12. Intake Manifold Questions

    An upgraded intake manifold can be highly variable in cost. Just an IM is a good upgrade because it'll bring down IATs and make performance more consistent. Price is as-listed. If you start adding port injection, price jumps a lot. Add injectors, ab auxiliary low pressure pump, a controller...
  13. Spool Performance 8hp5x stage 2 transmission kits

    Spool is a legit company, but to my knowledge nobody here has ever posted about it. It's quite the undertaking to do your own trans build. Lots of specialty knowledge. Wishing you good fortune if you decide to DIY. No rating on the hardware would push me away, though.
  14. What's your opinion on this?

    Garrett, Precision, and Borg Warner all are wholly made in China and/or use significant percentage of their components from suppliers in China. Garrett is China Precision is made with Chinese parts and/or Chinese ODM-licensed designs Borg Warner actively advertises significant portion of their...
  15. Help me identify this part number

    There is no part number for this O-ring. You will have to purchase a new hose, or measure the existing O-ring ID/OD/thickness and find an analogous option from variety packs on Amazon.
  16. Help: Hose Insulation Shredded

    I'm sure a velcro aluminized sleeve (example) would do the trick.
  17. Scam report on B58 Shop

    BBB is a paid service. It's not a bureau. You can literally just buy a nice rating, or pay to have bad ratings removed. It's a scam. OP needs to contact law enforcement and open a police report for fraud, because that's what is being alleged. Based on the lazy math I've done for OP's post, the...
  18. Toyota Teases GR Line Up: Supra MK6, Celica MK8, MR2 MK4, 86 MK3 and GR GT

    You know what? I choose to believe. Fuck it.
  19. You Won't Believe This!

    Came real close to getting screwed over.
  20. Exhaust setup for 2021+ Supras for maximum Burbles?

    Burble is (mostly) in the tune, not the exhaust. Switching to a catless downpipe and a large diameter exhaust will accentuate the effect.
